3.9.4 Stiffener tubes
For certain assembly situations (very large distances to fixing points) it may be necessary
to protect the anchoring tubes against buckling.

The actual pressure forces in the tube must be calculated us-
ing the forces stated in the tables.
If the specified forces are exceeded, additional measures must
be applied.
The table applies for smooth, one-part steel tubes without joint.
